Baking soda is something almost everyone already has tucked away in their pantry, yet this small box delivers surprisingly powerful cleaning results. It’s affordable, versatile, and effective in everything from scrubbing away grime to absorbing stubborn odors. When used correctly, baking soda can replace or boost many traditional cleaners in your home.
That said, baking soda isn’t a magic fix for every surface. Knowing where it shines and where it can cause more harm than good is key. Below, you’ll learn the best ways to clean your house with baking soda, how to use it properly, and a few common mistakes to avoid.

Using Baking Soda as a Gentle Scrub Paste
One of the most effective ways to clean with baking soda is by turning it into a simple scrub paste. All you need to do is mix baking soda with a small amount of water until you reach a consistency similar to runny toothpaste. This texture is ideal because it spreads easily while still providing enough grit to scrub away stuck-on grime. If the paste feels too thin, add more baking soda. If it becomes too thick or clumpy, a splash of water will bring it back to the right consistency.
This paste works exceptionally well on greasy surfaces, especially ovens. Over time, baked-on grease and food residue can become incredibly difficult to remove, but baking soda helps break through that buildup without harsh chemicals. It’s a great natural option for anyone looking to avoid strong oven cleaners while still getting real results.
The same paste can also be used in bathrooms on tubs, showers, and sinks where soap scum tends to collect. The mild abrasiveness gives you extra scrubbing power to cut through residue that regular cleaners often leave behind. Baking soda paste can even help with scuffs and crayon marks on walls. Apply a small amount to a microfiber cloth and gently scrub, being careful not to apply too much pressure. Flat paint should be avoided altogether, as baking soda can damage the finish and cause noticeable marks.
Whenever you use baking soda as a scrub, it’s important to test a small, hidden area first. Although baking soda is generally gentle, it is still abrasive. After cleaning, always rinse thoroughly. Any leftover residue can dry into a hazy white film that makes surfaces look dull or dirty. When cleaning areas like ovens, using smaller amounts and rinsing between passes will prevent baking soda from collecting in hard-to-reach crevices and creating unnecessary cleanup later.
Deep Cleaning Tile and Grout With Baking Soda
Baking soda becomes even more powerful when paired with hydrogen peroxide for cleaning tile and grout. Mixing equal parts baking soda and hydrogen peroxide creates a paste that’s perfect for lifting grime from porous grout lines. The consistency should again resemble runny toothpaste so it can easily sink into cracks and crevices.
This mixture works especially well in bathrooms where grout often harbors mold, mildew, and pink bacteria. Hydrogen peroxide helps kill bacteria while baking soda loosens and lifts the buildup, leaving grout noticeably brighter. Apply the paste to the grout lines, scrub gently with a toothbrush or nylon brush, and allow it to sit for a short period so it can fully work.
Rinsing thoroughly is critical once you’re finished. Any leftover baking soda can leave a chalky film, especially on darker grout. Because grout is highly porous and holds onto stains easily, you may need to repeat the process more than once for heavily soiled areas. Patience is key, and multiple passes often deliver the best results.
Removing Stains From Natural Stone Countertops With a Baking Soda Poultice
For stubborn stains on natural stone countertops, baking soda can be used in a different way by creating a poultice. This involves mixing baking soda with water to form a thicker paste that stays in place rather than spreading. The goal is to allow the baking soda to sit directly on the stain and draw it out of the stone’s pores.
Once applied, cover the area with plastic wrap and secure it using painter’s tape to avoid leaving sticky residue behind. Poke a few small holes in the plastic wrap to allow airflow, then let the poultice sit for up to 24 hours. During this time, the baking soda works to absorb the stain from deep within the stone.
Natural stone is porous, which means spills like turmeric, coffee, or brightly colored drinks can soak in quickly if not cleaned right away. Removing these stains often takes multiple applications, but baking soda is one of the safest and most effective options for this job. Consistency and patience usually pay off.
Absorbing Odors Naturally With Baking Soda
Beyond scrubbing, baking soda excels at absorbing odors rather than masking them. The most common example is placing an open box in the refrigerator, where it neutralizes food smells over time. However, baking soda eventually becomes saturated and stops working, which is why replacing it about every 30 days is important.
A simple alternative is creating small odor-absorbing packets using coffee filters and rubber bands. Fill the filter with baking soda, secure it tightly, and place it in areas prone to lingering smells. Shoes, especially gym shoes, are a perfect candidate. Baking soda absorbs odor molecules, helping eliminate smells at the source instead of covering them up.
These packets also work well in trash cans, closets, or anywhere you notice a musty odor. Just remember to replace them monthly so they stay effective.
Boosting Laundry Performance With Baking Soda
Adding baking soda to your laundry is an easy way to improve cleaning performance. About half a cup added directly to the washing machine drum helps balance the pH of the water, allowing detergent to work more effectively. This results in cleaner clothes and better rinsing.
Baking soda also helps neutralize odors, making it especially useful for gym clothes or towels that tend to hold onto smells. It can brighten whites, enhance colors, and even soften fabrics slightly. While baking soda isn’t a replacement for detergent, it’s an inexpensive and effective way to boost your laundry routine without adding harsh chemicals.
Using Baking Soda to Safely Put Out a Grease Fire
While not a cleaning task, baking soda can play an important role in kitchen safety. In the event of a small grease fire, baking soda can help extinguish flames by cutting off their oxygen supply. Water should never be used on a grease fire, as it can cause the flames to spread rapidly.
Ideally, every kitchen should have a fire extinguisher or fire blanket on hand. However, if one isn’t available, carefully sprinkling baking soda over the flames can help put them out. This is an emergency-only solution, but knowing it can make a critical difference if the situation arises.
Removing Tarnish From Silver Without Scrubbing
One of the most satisfying uses of baking soda is removing tarnish from silver without any scrubbing. By lining a container with aluminum foil, placing the tarnished silver inside, adding baking soda, and pouring in hot water, you create a chemical reaction that transfers tarnish from the silver to the foil.
Silver tarnishes when it reacts with sulfur in the air, forming silver sulfide. This method reverses that process, restoring shine without abrasion. A slight sulfur smell during the reaction is normal and indicates that it’s working.
This technique is excellent for silver jewelry, utensils, and decorative pieces, as long as the silver makes full contact with the foil. Delicate jewelry with fragile stones should be handled professionally to avoid damage.
Places You Should Never Use Baking Soda
Despite its versatility, baking soda isn’t suitable for every situation. Mixing baking soda with vinegar may look impressive due to the fizzing reaction, but once the bubbles stop, you’re left with salt water that offers little cleaning power. These products work better when used separately.
Another common mistake is sprinkling baking soda on carpets, rugs, couches, or mattresses. Baking soda particles are extremely fine and nearly impossible to vacuum up completely. Over time, they can clog vacuum filters and damage the machine. There are safer, more effective ways to deodorize fabric surfaces.
Using baking soda with acidic ingredients like lemon juice on cutting boards can also cancel out its cleaning power. While baking soda can help absorb odors from cutting boards, salt often works better for this task. Baking soda should also be avoided on delicate finishes, certain natural stones, and flat-painted walls where abrasion can cause visible damage.
Baking soda truly earns its reputation as a multi-purpose household staple. From scrubbing and deodorizing to brightening laundry and restoring silver, it’s one of the most cost-effective tools you can use to keep your home clean. The key is understanding how to use it properly and knowing when to choose a different method.
When used thoughtfully, baking soda can simplify your cleaning routine while reducing the need for harsh chemicals. It may be small, but this humble box packs a lot of cleaning power.
